When you see Hall on stage, he's full of piss and vinegar, but as he sits in his dressing room, barefoot and in jeans, a T-shirt and painted nails, he's reflective and gentle. He chooses his words so carefully that you can't help but hang on to every one.

Hall as Hedwig is a physical goddess, thigh muscles rippling as she struts across the stage one minute, then the next minute lowers to a full knee bend, crouching and jumping, climbing the side of the stage a second later.

Even the less strange characters get on your nerves by the end. It's difficult to see through all of the muck that makes up these people's lives, particularly when trying to have compassion for Bob, played by Letts, who is suffering from a degenerative nerve disease.
